Brain Development

Question 1

what is plasticity

Answer 1

the ability for a brain to adapt and change in response to a change in its environment

Question 2

developmental plasticity

Answer 2

development of new neural pathways in childs infants and adolescents

Question 3

5 stages of developmental plasticity in order are

Answer 3

1. proliferation
2. migration
3. circuit formation
4. synaptic pruning
5. myelination

Question 4

proliferation is

Answer 4

destined cells to become neurons multiply by 100,000s

Question 5

migration is

Answer 5

newly formed neurons move to destined area

Question 6

circuit formation is

Answer 6

axons of new neurons target new cells and form synapses with them

Question 7

synaptic pruning

Answer 7

old synapses/neurons are pruned away/got rid of

Question 8

myelination

Answer 8

production of new myelin sheath for axon terminals

Question 9

myelination is important for

Answer 9

myelin sheath, insulates axons, speeds transmission, messages and aids coordination

Question 10

adaptive plasticity

Answer 10

ability of brain to adapt and change throughout life, diminishes with age

Question 11

synaptogenesis is

Answer 11

process of forming new synapses

Question 12

sensitive period is

Answer 12

times in which are beneficial for a person to learn certain things due to nature of growing brain

Question 13

changes to brain during adolescence include

Answer 13

cerebellum, increase in neurons and synapses
amygdala, becomes more active
corpus callosum, thickens and increase in connections between two hemispheres
frontal lobe; motor movement and higher order thinking

Question 14

adaptive plasticity

Answer 14

ability for the brain to change and develop as a result of new experienes.
